The attachment of; the former to the bur is not so rigid as to irwnt theA itly to the right or left by moons of the olt and the slotted cross bor 28. This lateral ad- :i5 justxnont of the former is .advantageous in; that by means of it I cancause the former to occupy a position inclined more or less, to thc rightor left to meet and ohviate tendf.

2, tapers toward the delivery end and is wider or flared laterally so that the strip of aper will be caused to leave the .ti of the ormer in flattened and smooth con ition At a point beyond the tension device or drag 32 (inthe direction of travel of the paper strip) 'I mount a reservoir 39 fora suitable adhesive, said ,reservoir havin a nozzle el), the out-letof which is contro led by a spherical valve or ball 41 (see Figs. 4 and 5). flow of the adhesive, and at the same time said ball is caused to revolve by the movement of the edge portion of the paper under it so that said ball will act as a roll to apply a narrow stripe of adhesive to the surface of paper beneath it. As the reservoir is adjustable as hereinafter described, even to the extent of moving it entirely away from operative posit-ion, the ball t1 acts as a valve to completely close the opening in the lower end of the nozzle '40 whenever there isnothing under the ball to hold it raised. As a matter of inet, Vthe reservoir and its nozzle is capable of such accurate adjustment that the bail 41 is raised as soon as the front edge of :i new strip of paper is passed under it, the ball falling to its seat and closing the outlet for adhesive as soon as the last end rof a strip of paper has passed it, so thatno adhesive can escape toward the former excepting when the machine is in use. As shown in Fig. 5, the adjustment v.of the reservoir nozzle is such that the paper itself will so fill up the space between the former 24 and the.

lower end of the nozzle that the adhesive will not escape if the feed of the paper a should 'be stopped.

I will now y"describe the means of obtaining the accurati-adjustment'of the reservoir nozzle :V-..I,he. reservoir is provided with astrid lf2 (Figs. 2 and 4) into 'which an arm 43 extends, ascrew 44 passing upwardly througlrthe/stu 42 and engaging the arni 43 enabling the .reservoir to be secured to said arm in a more or less laterally inclined position. Oi course, any adjustment of lateral inclination of the reservoir will also vary the lateral inclination of the nozzle 40. The arm 43 projects from a block 45 which is mounted on a depending rod 46 and held in vertical adiusied position on said rod by a binding screw 47. The rod 46 depends from a block 48 which is mounted upon a cross rod 49 and secured in lateral position upon the latter by' a binding screw The cross rod i9 issu ported by suitable uprights 51. lf an hesive is employed which requires being irept warm, the 'means for heating the reser voir may consist ci? suitable ges burner f Alef-ins for directing .the heat to the Voir, conventionally illustrated. at 52 The ball 4l prevents too free Asbest shown in Figs. 1 and 5 the nozzle 40 acts to deflect one of the edges of the pgrer strip, or in other words, to hold that ge up while the ball His applying the stripe-of adhesive, the paper immediately after` passing the nozzle and deflector 40 returning to contact with the opposite edge portion of the strip so that the paper flap will descend upon the stripe of adhesive.

In orderthat the strip of paper will be caused to follow the contour o the tapering former and to run smoothly and` without wrinkling there-over in the direction of the length of said former, I provide a flexible member 53 which may be properly ref erred to as a folder or smoother ecause it insures 4a complete folding of the strip to tubular form and to insure its Ypassing to 'the feed or drawing and pressing rolls smoothly., This .folder or smoother crnprises a strap of suitable flexible material such as leather, said strap having a loop 54 at one end which may be conveniently engaged with one of the uprights 51, the. said strap being wound spirally around the paper upon the former and attached at its other end as by a screw lo any suitable fixed point. This latter point of attachment is best shown in Fig. 9, Fig. l merely indicating it diagrammatically. Oi. course, one end or the other of the strap 53 must be detachable from' its. fastening, and the strap'unwrapped, whenever a new strip of paper is to be started through the machine, the strap 53 being then returned to the position indicated in Figs. l, 2 and 9.

The extreme tip of the former 24 extends almost to the nip of two rolls (s ee Figs. 1, 2, 9, l0, 11 and 12)A having their bearings in suitable brackets 56, the upper roll having its bearings preferably springp'ressed in a well known manner such as 1ndicated in Figs. 1l and l2. The t-wo rolls have interineshing gears 57, and the shaft on the upper roll has a handle or thumb Wheel 58 by means of which the rolls can be moved manually, as when a new strip at paper is being introduced.

The shaft on the lower roll has afriction disk 59, the outer 4taco of which 1s engaeed by a friction driver 60 mounted upon shaft 61 and connected to said shaftI so as to rotate therewith, although adgiistable along the shaft by the mechanism herein-l after described.

The shaft 6l is the pow r shaft of the machine and has fast and -loose pulleys 62, vfor the driving belt 64. A shipper bar 6.5l is mounted to slide in an upright guide G6 (Fig. 10), said bar 65 being shifted in the direction of its length by an arm 67 o a rock shaft 168 mounted in suitable bearings and havin a handle or thumb wheel 69 {Fg. 9). he shaft GS is mounted at 108 is a disk 11'2 havin a peripherai notch or recess 118. A shiel 114 pivotally sup ported at 115 to a suitably fixed point, ha'L a tooth or lug 116, the outer face or edge oi' the shield being curved conoentricaily with the ratchet wheel.

Before describing the object of this con struction, I will explain that the same shaft t 108 carries and rotates a roll 117 (Fig. 14) which supports one end of a conveyer belt 118, the other end of said belt being mount.- ed upon a roll 119 upon a shaft 120 supported by bracket arms 121 and 13). As each tubular section is cut oif, it drops on to the belt 118, said belt being given an intermittent motion so that the surf csively deposited sections will overlap as cated iny Fig. 7, wherein each of the sc. ot' the tubular series is indicated at a'. The shield 114, when in the position shown in Fig. 15, permits the paWl to advance the ratchet wheel, and consequently the conveyer belt, a distance of one tooth of the ratchet wheei, This is because the said shield )mida the end of the pawl 110 with said pawl riding along the outer curved face o't the shield until it escapes from the inner end o'l portion so as to drop into enga tnx-nt nitfi the ratchet wheel, the point of dropping beA ing such that only the last portion of move-- ment of lever 107 wiil cause the pawi to actuate the ratchet Wheel a. distano@ of one tooth. The notched disk 112, however. also rotating with the shaft 10S and the ratchet Wheel. 'When the notch or recess 113 arrives underneath the lug; 116 :i the shield, said shield drops and thereby' ,een mits the paul 110 to engage a tooth of the ratchet Wheel 'farther away from vii-e pivot of the shield so that the noirs movement of the lever 107 will cause the patri to aci; iate the ratchet a disant-e of' severai teeth. This therefore imparts an excess iotion to the belt 118 so that all. of the tmiuiar sections previously deposited 7will he ax with the belt and leave a space rendi ceptible to the attendant to enabie thf l to gather up in one bunch ai of forniti' and closely deposited sssttions. i desired, since the number o1' sections in. th group wiii be`predetermined, :h iis 50 c 10Q. theyv can be then pausini;`l` words, the machine provides for the deposited sections as they are t. by the machine, `nto groups having y e termined quantities.

It is sometimes desirable that the strip et paper converted. into a flattened *une shol'f not be cut into sections but be Wound in a I sockets 123, and has at one end a pulley 125g engaged b v a belt 126 which also engages a pulley 127 carried by an extension 128 of the shaft 61. A yoke pendant 129 having pulleys 130 engaging the belt 126 is provided With variable Weights 131. This drive connection permits the belt to slip so as to compensate for the ffraduallv increasingr diN ameter of the roll being Wound up. The relative sizes of the pulleys 125 127 are such that when the Winding,r of the roli is first commenced it will have sufficient peu ripheral speed to take up the tuliing adranced by the feed rolls 55. As the die :mieter o the wound up roll increases, the wii begin to sip ou one or the other of the pulteys. the cmistruction there ,fore providing for a rictional drive of the reci shaft 1274s Secured o the Ashaft 11:24 is drinn 132 (Figs. and 16') having longitudinal re cess Sii in which a lever ifi-1 is pivoted at 5, aid lever' having a cani end 136 which enraged by an adjusting ring;F 137 which is preferably @flier-nelly milled as shown in Fig. This ring; is. internaily threaded tc it threads 139 at one end or' drum 132 so that aid ring is shifted. inwardly along the drum, it will engage the fam 1391 and muso the inner end of the lever 134i to profec'gd from the recess 1533 so as to bind against ilu-1- innci Wall of a core '132). inthe operation of this portion of the machine, :i for@ 125* is slipped to the posiion shown iu Fig. 16 and one end of the tube that is beingJ made, is suitably secured to said core. The ringV 1237 is adjusted so as to actuate the i3-1- as sl ribed to engage the core 139 and cause i. to rotate with the drum 132 and shaft 1211. The guide roll 14") (Figs. iti and 11i) is supported by uprights 141 to direct the tube of paper a to the reeling or As the ,ions of the seferal parts o1 the niafxiiiie ,rave been explained in connec tion with the description of the structure, further explanation of the operation of the machine as a whole will. not bc necessary.
